This invention relates to window constructions, particularly for railway cars or other vehicles; and particularly to double windows mounted with Vau air space between them ior'alr conditioned -a cars or vehicles or other structures. and has for its object a window, construction by which a single tirelike member betwe'en one oi the windowclosures or' the panelthereoi andthe window vframe'serves to lo both closures of a doubleblosuresaiid also vto se'ai the joint between the closuresior panels.A -It further has tor its object a particularly simpleand eillcient comtruetion by which one of the closures is mounted in the window frame and held Ytherein by the other closure clamped against it so that whenwthe latter closure is removed, either for l" windows or replacing the' glass, the other closure may also be removed. it desired. v n It further has for its object a simple cam means by which the removable closure is Aheid in position, and said cam means operableupon move'- ment oi the removable closure vertically direction parallel to the plane oi the closures. The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like 3 characters designate corresponding parts in all the views.

thepurpooeotwashingthe` orinaV movement of the sash I2 eachl'including a glass panel and circumferential frame members,the closure 'I being to the outer side of the car body. and the closure l on the inner side. The closure I includ a circumferential tirelike member S of compressible resilient 5 material, as rubber. coacting with the bottom I0 of the channel-2 and with the side wall oi the angular channel. 'I'he tirelike member 8 is here as mounted directly upon the margin of the glass panel and in eilect conl0 stitutes a sash frame. It is shown as formed with a circumferential ilange or lip II for coacting with the bottom Il of the channel. This lip Il is for the Purpose of compensating for variations in the size of the pane or the window open-v 15 ing and operates to frictionally hold the closure or panel l in the channel, when the closure 8 is removed. The closure. is here shown as including a sash'irame I2 having a groove for receiving the 'margin of the glass panel. a suitable-packing 80 and' Sealing strip I3 oi rubber being interposed between the margin oi the glass and the walls oi the groove. The frame I2 compresses against the opposite sidev of the tirelike member 9 to that y side engagedwith the side wall of the channel 2 as of the window frame. 1 Themeans for clamping the closure l or the i'rame I2 thereof against the tirelike member inf cludes cam means on the frame I2 and the window frame I and operating to clamp or wedge the I0 frame I2 against 1the tirelike member 9 upon in a direction parallel to the plane of the closures 'I or 8. The ciamping means includes two sets of elements, one set being provided on the sash frame I2 at spaced 36 apart points circumferentiaily around the same, and the other set being mounted on the window v frame, and one set having wedge surfaces inclined relatively to the plane oi the closures or panels and enacting with the other set, as the n Vclosure I is moved in a direction parallel to the In the illustrated embodiment oi the invention, the sash I2 is provided at the edges of the stiles or uprights thereof with cam elements Il includ 45 ing base plates secured to the edge of the stiles or uplihtso'i thesash I2 and hookfshaped cam portion extending toward the frame I and concting with keeper on the frame I. As shown, the hook-shaped portions extend through slots 50 or openings Il in thefram'e I, wetboek-shaped portions being provided with `inclined or` cam faces II coacting with the lower end walls of the slots with a comming action, these end walls The sash I2 is of greater height and width than the closure 1 and the elements Il are located beyond the edge of the closure 1` and the tirelike member 9 thereon. The slots I8 are formed in a flange I8 extending outwardly from the bottom of the flange 2 and pressing at I! against a step or shoulder on the bracket 5. 'I'he screw 4 extends through the ange I8.

The top rail of the sash I2 is provided with cam elements spaced apart on the upper edge thereof and having hook-shaped portions 2I for entering notches or slots 22; The hook-shaped part 2| is fori'ned with an,inclined or cam surface 23 for coacting with the keepers orbottoms 2 4 of the notches 22. The bottom rail of the sash I2 is provided with hook-shaped elements 25 formed by providing the bottom rail with a lengthwise recess 26, these elements 25 coacting with hook-shaped elements or keepers 21 secured to the ange I8. 'Boththe surfaces of the element 25 and the hook-shaped part 21 are formed wedge or cam shaped.

In operation, assuming the inner or movable closure is placed in position by rst passi'ngthe hook-shaped, element 2l through the notches 22 while the sash is held in slightly-inclined position; then swinging the sash I2 into @position parallel with the closure 1 and then pushing down on the sash I2 or letting it drop, thus engaging the elements I5, 2li` and 21 with the slots I6, 22 and hook-shaped parts 26 on the frame I. Owing to the inclined surfaces I1, 23, 21, the closure 8, or the sash I2 thereof, is pressed against the tirelike member 9. The slots I6, 22 are wider than the hook-shaped parts I4 and 2l. Thus, when the sash I2 is firmly clamped against the tirelike member, it is in sealed relation thereto, so that the space between the panelsis sealed and also thetirelike member acts as a cushion for the closure 8 as well as for the closure 1.

-Suitable fastening means, as a screw 28, may be provided for holding the sash I2 from working loose under vibration of the vehicle, and also a suitable handle 29 may be provided along the rail of the sash I2 for assisting in demounting it. Also, if desired, after the sash I2 has been lifted to disengage the hook-shaped parts Il and 23 from the notches 22 and slots I6, the lower'end may be tilted outwardly slightly and then again dropped to again engage the hook-shaped parts 23 with the bottom walls of the notches 22 so that the hook-shaped parts 23 then act as hingeleaves to permit the sash I2 to be swung inwardly with the hook-shaped parts 23 serving as hinges. 5

A suitable container 30 for a moisture-absorbing material, as activated alumina. 3|, may be placed between the closures 1 and 8 or the glass panels thereof. VThe edge of the sash I2 rims close to the interior trim of the car body, the 10 formed with a windowopening; of a pair of parallel closures mounted relatively to each other to have an air space between'them, one of -said clo- 5gg;
